Gumilla longicornis (Walker) 
Osmylus longicornis Walker 1853: 235. Holotype: “Georgia,” “Type, Osmylus longi- 
cornis Walker, det, D. E. Kimmins”, “Gumilla longicornis Walk., Long. Navas 
det.” BMNH. 
Meleoma longicornis , Hagen 1861: 210. 
Leucochrysa longicornis, Banks 1907: 26. 
Gumilla ? longicornis, Navas 1912: 189, Kruger 1913: 221. 
Allochrysa longicornis, Bickley and MacLeod 1956: 184. Not A. longicornis (Gray), 
Banks 1920: 339, as cited by Bickley and MacLeod 1956: 184. 
This insect is not a chrysopid, but an osmylid in which the ocelli 
are lost, and the antennae are exceedingly elongate. Hagen’s re- 
ferral of G. longicornis to the chrysopid genus Meleoma seems to 
have been based solely upon the nature of the antennae. Navas’ 
illustration of the wing characters is reasonably accurate. Addi- 
tional features are: pronotum articulating above mesothoracic spi- 
racle, claws simple, single aroliar pad, two nygmata between RS- 
MA and MP in forewing. In hindwing, basal piece of MA (“sinu- 
ate crossvein”) absent, stem of MP runs close to R; MP2 fused 
briefly with and appearing to be a continuation of GuA; CuP un- 
branched, clearly separate from 1A for its entire length. Wing 
membrane microtrichiated, marginal vein entire except for a few 
marginal dots near wing apex. 
The only other species of this genus, Gumilla aspersus Navas 
1912: 189, known from a single male specimen from Brazil (Vienna 
Museum, not seen) is probably the same; Navas’ figure of the fore- 
wing does not differ in any important respect from that of G. longi- 
cornis. Two additional specimens from Brazil, Langsdorf, are in 
the Berlin Museum. There thus seems little question that the type 
of G. longicornis is also from Brazil, not Georgia.
